What is an IBAN?

An IBAN (International Bank Account Number) is an internationally agreed format for bank account numbers to facilitate accurate cross-border payments. The IBAN contains key details about the recipient’s bank account, including country, bank branch, and account number.

The IBAN consists of up to 34 alphanumeric characters and contains a two-letter country code, two check digits, and a Basic Bank Account Number (BBAN) that has up to 30 characters. This standardized format enables automated processing of international payment transactions.

IBAN Format

The IBAN format consists of a two-letter ISO country code, followed by two check digits, and a BBAN containing additional details like bank, branch, and account number. The length of IBANs varies by country but can have up to 34 characters.

For example:

Country code + Check digits + BBAN GB23 MBTC 6016 1331 9268 19

IBAN Length

While IBANs contain 34 characters at max, the length varies by country. Countries determine the actual IBAN length to use based on their existing bank account number standards.

For instance, IBANs for British bank accounts contain 22 characters. German IBANs have 22 characters as well, while IBANs from Spain have 24 characters.

IBAN Structure

The IBAN contains important details in a standardized structure:

  • 2 letter country code – Identifies country
  • 2 digit check number – Validates IBAN accuracy
  • 4 letter bank code – Identifies the bank
  • Account type identifier – 1-9 characters to ID account use
  • Account identifying number – Up to 30 alphanumeric characters

This information together facilitates electronic transfers, especially across borders.

IBAN Uses and Benefits

Key uses and benefits of the IBAN include:

  • International transfers: Enables seamless movement of money between countries
  • Error reduction: Minimizes mistakes with standardized format
  • Faster payments: Facilitates straight-through processing without manual checks
  • Additional validation: Extra verification through check digit calculations
  • Automated reconciliations: Simplifies bank statement reconciliations

Using an IBAN provides significant advantages for managing finances globally.

IBAN code for Metro Bank Plc

The specific IBAN format used in the UK is:



  • GB = Great Britain country code
  • xx = Two-digit check number
  • BANK = 4-char bank and branch ID
  • XXXX XXXX XX = Account number

This contains key information to identify recipient accounts.

UK IBAN Format

The UK IBAN is structured into several components:

  • GB country code
  • Check digits
  • 4-char bank code
  • 6-digit sort code
  • 8-digit account number

Including the check digits, UK IBANs contain 22 characters.

Check Digits

The two check digits within the IBAN are calculated using the MOD 97-10 algorithm on the rest of the IBAN characters. This verifies the integrity of the full IBAN string.

If a single digit is entered incorrectly into an IBAN, the check digit calculation will fail, and the IBAN is invalid. This provides an extra verification safeguard.

Sort Code

The 6 digits after the 4-character bank identifier represent the sort code. This identifies the specific UK bank branch holding the account.

Sort codes are assigned uniquely by financial institutions. Including the sort code ensures payments route accurately.

Account Number

The final 8 characters constitute the actual bank account number. This uniquely identifies the individual recipient’s account at the financial institution.
